Toyota has announced that the 2010 Toyota Auris HSD, or Hybrid Synergy Drive, will officially go on sale in Europe later this spring. The car uses a 1.8-liter petrol engine and electric motor to provide nearly 62 mpg (US), consuming 3.8 liters of petrol per 100 km.
The petrol engine version it’s powered by a 1.8 L and a 60kW (80bhp) electric motor mated to a 27kWh nickel metal hydride battery. The car’s total power reaches 134bhp and can be driven in electric mode up to 30mph for 1.2 miles. The HSD meets Euro5 emissions standards and is expected to also comply with forthcoming Euro6 requirements. Auris HSD is scheduled to go on sale in July. Further details of performance, technical specifications, model grades and equipment features will be announced nearer the launch date.
Exterior design: a stronger, more confident road presence
Redesigned bumpers have increased the front and rear overhangs by 15 mm and 10 mm respectively. As a result the Auris 2010 has increased in overall length by 25 mm to 4245 mm, while the long, 2600 mm wheelbase remains unchanged.
With a new horizontal bar-type grille, more aggressive headlamp clusters, LED daytime running lights and a wider lower bumper air intake, the entire front of the Auris 2010 has been restyled to enhance the car’s stable, ground-hugging stance and create a more youthful image.
The rear design has been strengthened to provide a stronger, more confident road presence. The bumper corners have been extended outwards and create a new ‘catamaran’ bumper profile which accentuates the Auris 2010’s muscular proportions and wide track.
The latest addition to the model line-up, the Auris HSD incorporates several unique exterior design features which both improve the car’s overall aerodynamic efficiency and indicate the presence of Toyota’s Hybrid Synergy Drive® powertrain.
The upper grille opening has been optimised to help the air flow smoothly over the upper half of the body, and the size of the lower grille has been enlarged to reduce airflow resistance as well as improving engine cooling efficiency.
Housing a revised foglamp configuration, the flat, vertical surface of the bumper corner not only reinforces the Auris HSD’s broad stance and driving stability, but also corrects airflow as it passes over the front wheels to minimise wheel arch turbulence.
Allied to a 5 mm lowering of vehicle ride height and a choice of purpose-made, 15” or 17” alloy wheels with integrated, aerodynamic caps and low rolling resistance tyres, a large, roof mounted rear spoiler further improves the Auris HSD’s aerodynamic efficiency.
Acting in combination to smooth and control the flow of air over the car, these HSD-specific design modifications have reduced the Toyota hybrid’s coefficient of drag from Cd 0.290 to 0.283, effecting reductions in both fuel consumption and CO2 emissions.
The Auris 2010 is available in a choice of six exterior colours, including a new, hybrid-specific Pearl White finish.
Interior design: improvements in quality, ergonomics ?and visual appeal
Soft touch materials now cover the top of the driver’s instrument cluster and the upper glove box, and the seat upholstery has been upgraded across the range. The height of the centre console storage box has been raised by about 50 mm, and it now functions as an armrest. A new, more comfortable steering wheel incorporates redesigned audio and Bluetooth® phone control switches.
The unique, bridged centre console which brings the gear lever, handbrake and instrumentation within the closest possible reach of the driver has a new, bright metallic finish matched by the door handles. The handbrake design has been revised with a new lever release button, a tactile, ergonomic grip and lower seating in the release position.
Control panel colour and finish changes have enhanced switch layout visibility, and the illumination of the Optitron meter dials has been changed to white for improved clarity and visibility.
In conjunction with the introduction of Hybrid Synergy Drive®, the Auris HSD interior features several significant modifications. The driver’s instrument binnacle has been revised, with the tachometer replaced by an Eco Drive Assist Monitor. The centre-dial information panel includes additional, Hybrid Synergy Drive®-specific information such as Energy Flow and Eco Drive Result monitors.
A hybrid blue Smart Start switch has been added to the side of the instrument cluster. The centre console incorporates a Parking Control switch, EV, Eco and Power drive mode switches and a shift-by-wire transmission lever with a high-quality silver paint finish.
Auris HSD instrument and switchgear illumination has been amended to greenish white numbers on a hybrid blue background for the meter panel, audio and heating controls, and the Smart Start, Drive Mode and Parking Control switches.
A choice of hybrid-specific upholstery finishes features a standard specification, blue-flecked seat panel fabric, while high grade models are trimmed in Alcantara® panels with leather surrounds.
Powertrains and driving dynamics
- Hybrid Synergy Drive® full hybrid technology introduced to the Auris 2010 model range
- Toyota Optimal Drive technology applied to the full 3 petrol, 3 diesel engine range
- Overall Auris CO2 emissions support Toyota whole-fleet CO2 targets, already at 130 g/km in 2009
- All diesel engines available with Diesel Particulate Filter (DPF) or Diesel Particulate and NOx Reduction filter (DPNR)
- Revised suspension for improved ride comfort with high speed stability and secure handling
As a result of Toyota Optimal Drive technology, the Auris will be the first Toyota to comply with Euro 5 emission standards across the entire European model range by July 2010.
Starting at just 118 g/km, CO2 emissions have been lowered throughout the engine range, offering significant cost of ownership benefits to fleet customers.
The introduction of the Auris HSD will create an important shift in customer perceptions of full hybrid technology. The advantages of exceptional fuel efficiency and low CO2 emissions are obvious. However, the Auris HSD customer will also experience a smooth and sophisticated driving experience -unique to the C-segment- thanks to the everyday usability, driving comfort and remarkable quietness of Toyota’s multiple award-winning, full hybrid powertrain.
With remarkably low 89 g/km CO2 emissions the Auris HSD plays a significant role in further reducing Toyota’s whole-fleet CO2 average which, having fallen by 16 g/km between 2008 and 2009, already stands at just 130 g/km.
Hybrid Synergy Drive® - Full Hybrid technology
The new Auris HSD is a full hybrid capable of operating in petrol and electric modes alone, as well as a combination of both. Its Hybrid Synergy Drive® system delivers the energy-saving benefits of a series hybrid combined with the performance benefits of a parallel hybrid.
Full hybrid technology equips the new Toyota hatchback with impressive, seamless acceleration and remarkably quiet operation, while returning class-leading fuel efficiency and the lowest possible emissions.
The Auris HSD’s latest generation, series/parallel full hybrid system features a 1.8 litre VVT-i petrol engine, a powerful electric motor, a generator, a high performance battery and a power control unit. A power split device employs a planetary gear set to combine and re-allocate power from the engine, electric motor and generator according to operational requirements.
Key to the successful installation of Hybrid Synergy Drive® within the Auris front-engined platform, the electric motor, generator and power split device are all housed in one transmission casing the size of a conventional gearbox. The full hybrid drive system’s seamless, electric continuously variable transmission is controlled by shift-by-wire technology, using an electric shift lever system.
System power is provided by a lightweight, highly compact, 4-cylinder, 1798 cc, Atkinson cycle VVT-i petrol engine developing 98 PS (72 kW) at 5200 rpm and 142 Nm (105 lb-ft) of torque at 4000 rpm, and a high performance, permanent magnet, synchronous 60 kW electric motor generating a maximum 207 Nm (153 lb-ft) of torque from 0-13000 rpm.
Powered by the hybrid battery, the electric motor works in tandem with the petrol engine to boost acceleration during normal driving. The electric motor alone powers the driven wheels when the Auris HSD is operating in EV mode.
During deceleration and under braking, the electric motor acts as a high-output generator to effect regenerative braking. Normally wasted as heat, kinetic energy is recovered as electrical energy for storage in the high performance battery.
In combination, the 1.8 litre VVT-i petrol engine and electric motor generate a maximum system power output of 136 PS (100 kW), offering performance to match any conventional 2.0 litre diesel or petrol hatchback. Conversely, the Auris HSD returns low CO2 emissions of 89 g/km . In addition, the Auris HSD generates significantly lower NOx emissions than diesel engined cars of comparable performance.
Moreover, when operating in a unique, switchable EV mode, the Auris HSD offers zero CO2 and NOx emissions, driving for up to two kilometres at speeds of up to approximately 50 km/h, dependant on battery charge and driving conditions.
Unique Auris HSD eco driving experience
The Auris HSD offers four driving modes, including three on-demand modes, which not only maximise the capabilities of the Hybrid Synergy Drive® powertrain, but also incorporate comprehensive Eco driving support for those who wish to adopt more environmentally friendly driving techniques.
An EV mode allows for ultra-quiet running on electric motor power alone, resulting in zero fuel consumption and emissions; an ECO mode maximises hybrid system efficiency and fuel economy; and a POWER mode boosts system performance. In addition, an Eco Drive Monitor helps drivers maximise the fuel efficiency of Toyota’s Hybrid Synergy Drive® system.
Via the multi-information indicator in the combination meter, drivers may monitor the flow of energy within the Hybrid Synergy Drive® system for each driving mode. This helps them develop relaxed, fuel efficient driving techniques and maximise system efficiency. In addition, a simple yet clear power consumption gauge in the combination meter shows how much power is being used or generated at any given time.
Taking advantage of the inherent operational quietness of Hybrid Synergy Drive®, particular attention has also been paid to Noise Vibration and Harshness (NVH) reduction measures. This ensures customers enjoy a calm, quiet cabin environment at all vehicle speeds. Road and engine noise have been rigorously suppressed through the comprehensive use of sound-proofing materials. Full thickness glazing and an acoustic windscreen design further reduce wind noise for improved quietness at cruising speeds.
Toyota Optimal Drive applied to all petrol and diesel engines
Designed to optimise the balance of performance and driving enjoyment with fuel economy and low emissions, Toyota Optimal Drive focuses on several key aspects of powertrain development such as environmentally friendly technologies, low friction components, lightweight, compact design and enhanced combustion efficiency.
The application of Toyota Optimal Drive across the Auris range has significantly reduced CO2 emissions. The overall Auris CO2 average has been reduced from 152 g/km in 2007 to 142 g/km in 2009. In 2011, which will be the first full year of Auris range sales, the figure will reduce further to just 125 g/km.
1.33 litre Dual VVT-i with Stop & Start system
The 1.33 litre Dual VVT-i petrol engine generates 73 kW/ 99 DIN hp and maximum torque of 128 Nm at 3800 rpm, while returning an average fuel consumption of 6.0 l/100 km and CO2 emissions of only 139 g/km.
The unit benefits from numerous Toyota Optimal Drive engine optimisations. A combination of lightweight technology, a resin cylinder head cover and intake manifold, and a remarkably compact design has effected a substantial reduction in engine weight and size. Combustion efficiency has been improved through the use of a high efficiency intake port, a high compression ratio and long reach spark plugs.
Extensive friction reduction measures include enhanced engine block rigidity and bore circularity, an improved valve roller rocker arm design with a new camshaft profile, small, lightweight pistons with a low friction coating, low viscosity oil and a water jacket spacer.
Toyota Optimal Drive’s environmental technologies are represented by the application of a wide ratio 6-speed manual transmission and optional, Stop & Start System technology.
This innovative system automatically switches off the engine when the vehicle is stopped. The world’s first permanently engaged ring gear mechanism allows for automatic engine restart within half a second when the clutch is lifted, with significant reductions in engine start noise and seat vibration levels.
Thus equipped, the 1.33 litre Dual VVT-i unit’s fuel consumption and CO2 emissions are lowered still further, to just 5.9 l/100 km and 136 g/km respectively.
1.6 and 1.8 litre Valvematic petrol engines
The 1.6-litre Valvematic engine develops 132 DIN hp and class-leading maximum torque of 160 Nm at only 4400 rpm. When equipped with a 6-speed manual transmission, the unit returns a combined cycle fuel consumption of 6.6 l/100 km and generates CO2 emissions of only 152 g/km. MultiMode transmission further reduces both fuel consumption and emissions, to 6.3 l/100 km and 146 g/km respectively.
The 1.8 litre Valvematic engine develops 147 DIN hp and maximum torque of 180 Nm at 4000 rpm, yet the engine’s combined fuel consumption is only 6.7 l/100 km, and CO2 emissions are 155 g/km.
Through the application of Toyota Optimal Drive, both engines benefit from the same lightweight technology, compact design and combustion efficiency engine optimisations as the 1.33 litre unit.
In addition, friction reduction measures include an improved valve roller rocker arm design with a new camshaft profile, small, lightweight pistons with a low friction coating, enhanced engine block rigidity and bore circularity, and low viscosity oil.
The environmental technologies of Toyota Optimal Drive are represented by the application of wide ratio 6-speed manual transmissions and an optional, MultiMode transmission available with the 1.6 litre unit.
Offering class-leading efficiency, power and torque, Valvematic is a further development of Toyota’s highly successful Dual Variable Valve Timing-intelligent (Dual VVT-i) system.
Adding lift and duration control to the variable inlet valve timing to deliver more power for less fuel consumption with reduced CO2 emissions, Valvematic also reduces friction and pumping losses under light engine loads, further lowering fuel consumption.
The three diesel engines in the Auris 2010 model range also benefit from the extensive application of Toyota Optimal Drive technologies.
Lightweight technology and a compact design have resulted in a marked reduction in engine weight and size. Numerous combustion efficiency enhancing measures include a lower compression ratio, optimised combustion chamber dimensions, enhanced Exhaust Gas Recirculation (EGR) cooler efficiency and stainless steel exhaust manifolds with close-coupled Diesel Particulate Filters (DPF).
The adoption of Piezo injectors is of particular significance. Their high speed reaction time makes multi-phase high speed injection possible. This has the effect of both lowering the rate of combustion expansion and effecting a more thorough burn within the combustion chamber, thus further reducing particulate, NOx and CO2 emissions.
The 2.2 litre engine also benefits from Toyota’s Diesel-Clean Advanced Technology (Toyota D-CAT), which incorporates a Diesel Particulate and NOx Reduction filter (DPNR).
1.4 D-4D 90 diesel engine
The 1.4 litre D-4D engine develops 90 DIN hp and maximum torque of 205 Nm at only 1800 to 2800 rpm, and may be equipped with a Diesel Particulate Filter (DPF) for CO2 emissions that are amongst the lowest in the C-segment.
When equipped with the manual transmission and a CCo, the ?1.4 D-4D 90 unit returns a combined cycle fuel consumption of 4.7 l/100 km and generates CO2 emissions of only 124 g/km. Manual versions fitted with a DPF return just 4.5 l/100 km and a remarkable 118 g/km.
This outstanding, 118 g/km CO2 emissions performance has been achieved through combining Toyota Optimal Drive with various measures designed to maximise the aerodynamic and fuel efficiency of the Auris 1.4 D-4D 90, such as lowered suspension and low rolling resistance tyres.
2.0 D-4D 125 and 2.2 D-4D 180 diesel engines
With a DPF fitted as standard, the 2.0 D-4D 125 delivers ?126 DIN hp and maximum torque of 310 Nm from 1800 to 2400 rpm. Combined cycle fuel consumption is 5.2 l/100 km and CO2 emissions are 138 g/km.
The Auris’ powerful, 2.2 litre turbodiesel further benefits from Toyota’s Diesel-Clean Advanced Technology (Toyota D-CAT), which incorporates a Diesel Particulate and NOx Reduction filter (DPNR).
The 2.2 D-4D 180 unit delivers 177 DIN hp and a highly impressive maximum torque of 400 Nm between 2000 and 2800 rpm. Conversely, average fuel consumption is just 5.9 l/100 km, and CO2 emissions only 154 g/km.
6-speed manual and MultiMode transmissions
Every engine in the Auris 2010 range is mated to a Toyota Optimal Drive six-speed manual transmission featuring wide-spread ratios designed to optimise fuel consumption and lower CO2.
An optional, MultiMode transmission is available on 1.6 Valvematic petrol and 1.4 D-4D 90 diesel versions. MultiMode is an automated manual transmission with a fully automatic shift mode and no clutch pedal. It offers the driver a choice of two, fully automatic gear change modes or a manual, sequential gear change with steering wheel-mounted shift paddles.
Revised suspension and steering for an improved driving experience
Through close collaboration between Toyota’s European and Japanese Research and Development teams, the implementation of regional customer feedback and extensive European testing the Auris’ suspension system has been fine-tuned specifically for the customers and roads of the European market. It combines stable high speed driving performance with secure handling and superior ride comfort.
The Auris’ speed-sensitive Electric Power Steering (EPS) has also been revised and refined to provide better feedback and improved vehicle agility.
The Auris HSD brings the extraordinarily refined, smooth and silent Hybrid Synergy Drive® experience to a Toyota mainstream model customer base for the first time in Europe.
